A more congenial Rick Santorum doubled down on several controversial, and religiously laden, remarks in an interview Sunday morning on CBS’s “Face the Nation,” where he defended his recent claims that prenatal testing results in abortions, that federally provided education was “anachronistic,” and that President Obama’s policies are not “based on the Bible.”

“I’ve repeatedly said I don’t question the president’s faith,” Santorum told host Bob Schieffer, denying what some have said was a signal that Santorum had challenged the legitimacy of Obama’s Christianity. “I’ve repeatedly said that I believe the president’s Christian — he says he’s Christian. But I am talking about his worldview, the way he addresses problems in this country, and they’re different than most people view it in America.”

In a speech to Tea Party conservatives on Saturday in Columbus, Ohio, Santorum had dismissed Obama’s politics as being based in “some phony theology.”

“It’s not about you. It’s not about your quality of life. It’s not about your jobs,” Santorum said. “It’s about some phony ideal, some phony theology. Oh, not a theology based on the Bible. A different theology.”
